I fixed a couple bugs on wing creator and more importantly, changed the user locators to define the wing. It now doesn’t use user defined locators, it takes the bounding box of key feathers and uses that to judge the shape instead. This way it requires no input for the user other than that of the feathers and clicking the buttons! You can still change the shape/scale of the feathers once they’re generated and before generating the motion system and it will work. Enjoy!
